AB C. Measuring Fluid Pressure

Special tools: 951 2782, 999 2531, 999 5074, 999 5114

Note!
Before calling Volvo Tech Hot Line: 1-800-500-5570, all fault tracing must have been performed, check sheet filled out and pressure readings taken.

Measuring fluid pressure

Measuring fluid pressure C1 and C2 AB C1

Warning!
The pressure must be checked with the engine idling only. Increasing RPM will damage the pressure gauge.





Remove the plug (Torx 55) and install special tool 951 2782 and 999 2531 (1) as per illustration.

Remove the plug and install special tool 999 5074 and 999 5114 (2) as per illustration.

Start the engine and move the gear selector into position N.

Measuring C1 AB C2

Apply the brake pedal.

Move the gear selector into position D.





The C1 gauge should read about 0.4 MPa (57 Psi) and the C2 gauge must read approximately 0 MPa (0 Psi).

Measuring C2 AB C3

Move the gear selector into position N, wait 3 seconds and then move it into position R.





The C2 gauge should approximately read 0.6 MPa (85 Psi) and the C1 gauge must read approximately 0 MPa (0 Psi).

If C2 pressure in step 2, and C1 pressure in step 3 showed other values than 0 MPa (0 Psi), the rear cover of the transmission must be replaced as per AB B1.
